Hi guys does it appear my corrector plate requires a clean?
Last night used one of those bulb shaped rubber blowers on close look there appears some black smudges on the upper right of corrector plate, there is also that white speck whatever it is. The smudges look a bit like finger marks but nobody else has been handling the scope. Or maybe that area is the normal bit and it's surrounded by layer of dust!? - see how little i know!
Not really sure have used the scope only few times over past 2 weeks where before it was in attic for over a decade
